TTTech to Provide ARINC 664 p7 Products for Mission System on UK AW101 Merlin Mk4/4a Helicopters

TTTech, the technology leader in robust networked safety controls, has been awarded a sub-contract by General Dynamics UK to provide ARINC 664 p7 end system cards for the Tactical Processor mission system equipment that will be installed onboard AgustaWestland’s AW101 Merlin Mk4/4a helicopters.

TTTech’s rugged end system cards increase the flexibility and functionality of General Dynamics UK’s mission system through the support of three traffic classes (Standard Ethernet, ARINC 664 p7 and Time-Triggered Ethernet SAE AS6802), with three channels at 10/100/1000 Mbit/s. The end systems are commercial-off-the-shelf (COTS) products, available in various form factors (PMC, XMC, PCI, PCIe, CPCI). TTTech’s AFDX and TTEthernet end system cards and switches for safety-, mission- and time-critical systems support deterministic real-time data communication with defined Quality of Service (QoS) as well as bounded latency and jitter.

"We are delighted to work with General Dynamics UK, a globally recognized leader in complex systems for aerospace and defense," states Kurt Doppelbauer, Vice President Sales Aerospace at TTTech. “This contract will serve as a basis for a successful long-term relationship between TTTech and General Dynamics UK on advanced system integration capabilities.”

TTTech’s end system cards will be used in General Dynamics UK’s mission system equipment, which includes the Tactical Processor system and a secure data recorder to provide increased performance and capability onboard the helicopters. This sub-contract is awarded as part of the Merlin Life Sustainment Programme (MLSP), which was awarded to AgustaWestland by the UK Ministry of Defence in January 2014 to convert 25 AW101 Merlin helicopters for maritime operations.
